Application led March, 1919. Serial No. 2853327.

VTo all wlw-mA t may concern.'

Be it known that I, ROBERT B. GALLOWAY, a citizen of the United States,and resident of Detroit, Wayne County, State of Michigan, have inventedcertain new and useful Improvements in lVindshields, of which thefollowing is a specification.

This invention relates to aircraft and particularly to a windshieldtherefor.

One object of the invention is to provide a windshield particularlyadapted for aircraft and which may be readily adjusted to differentpositions of angularity relative to a vertical plane, with one hand ofthe aviator.

Another object of the invention is to provide a windshield adapted to belocked firmly in various positions of adjustment and capable of-releasefrom such locking means by a lateral movement of the wind shield.

With the above objects and others in View, the invention is embodied inpreferable form in the `construction hereinafter described andillustrated in the accompanying drawings, in which- Fig. 1 is a frontview in elevation, partly in vertical section, showing the improvedwindshield applied to the fuselage of an aircraft; and

F ig. 2 is an end view.

Referring to the' drawings, 10 indicates the fuselage of an aircraftfrom which rises an enlargement or elevated body structure 11 havingbearings 12 for a transversely extending shaft 13. Brackets 14(zo-operate with the body structure 11 in forming said bearings and havefeet 15 which are fastened to the fuselage. rllhe glass of thewindshield is indicated by 16 and it is mounted in a frame 17 havingvertical, depending arms -18. At oneendof the shaft or rod 13, one

arm 18 ispivoted byameans of a suitable opening on said shaft betweennuts 19 and 20, the latter bearing against a washer 21 surrounding theshaft, and pressed against the bracket 14;' The arm 18 at the other endof the shaft also has a suitable opening through which the shaft extendsand it is prevented from escape beyond the end of the shaft by means ofthe nut 22 on oneside thereof. At tle other side of the arm the same 1spresse against by a s iral s rin]f 23, the opposing end of which sppringIbeargs against the supporting body in which the shaft 1s carried. Thespring thus tends to pressthe windshield to the right and maintain 1t 1nnormal position. In such posiytion the windshield is adaptcdto be lockedagainst movement around the shaft as a center. To this end each of thedependingr arms 18 1s provided with a toothed sector 24. 'lfhe recessesbetween the .teeth in the periphery of this sector are adapted to engagea head 25 of a stud 26 which stud is provided with a cutaway portion 27between the head 25 and thelbracket 14 to which the stud is riveted orotherwise secured.

In the operation of the device the sprin 2 3 normally presses thewindshield to the rlght retaining one of the notches of the sector 24 1nengagement with the head 25 of pin 26. To adjust `the windshield to adifferent position of angularity it is merely necessary to press thewindshield longitudinall'y to the left against the force of the spring`sufficiently to carryvthe arm 18 and itssector out of alignment with thehead 25 so as to release the teeth fromthe said head whereupon theshield may be swung to the desired new adjustment and then moved backagain to the right to engage the notch in the sector corresponding tothe new angle with the head 25.

Having thus described my invention, what ll claim and desire to secureby Letters Patent is I In a windshield structure, the combina- 4tionwith a support, of a windshield having a rod extending longitudinallythereof and mounted in said support, a toothed sector at each end ofsaid windshield, a detent mounted on said support adjacent each of saidsectors and adapted to positively retain the windshield in adjustedposition, and means for vyieldingly retaining said windshield in oneposition longitudinally of said rod whereby said Windshield may be movedlongitudinally out of locking position with said detent.

In testimony whereof ll a'ix my signature.

RBERT B. GALLOWAY.
